Description
The Euroquartz EMEM1001 oscillator range are MEMS (Micro Electro-
Mechanical System) devices offering excellent jitter and stability
performance over a wide range of supply voltages and temperature
ranges (up to -40° to +105°C). EMEM1001 parts incorporate an all-
silicon resonator that is robust and perfoms well in high shock and
vibration environments.
EMEM1001 oscillators are available in four, industry-standard SMD
packages: 7 x 5mm, 5 x 3.2mm, 3.2 x 2.5mm and 2.5 x 2.0mm. The
part may be 'dropped in' to most PCB footprints as standard crystal
oscillators.

Notes:
1. Absolute maximum ratings are those
values beyond which the safety of the
device cannot be guaranteed. The
device should not be operated beyond
these limits.
